SANITARY DRINKING GLASS Filed June 13, 1945 III Patented May 7, 1946 UNITED STATES PATENT OFFICE SANITARY DRINKING GLASS Grover C. Groom, Little Rock, Ark.

Application June 13, 1945, Serial No. 599,174

1 Claim.

The subject matter of the invention is a sanitary drinking glass of the general character described in my prior Patent No. 1,712,552, issued May 14, 1929, and this invention relates to improvements thereon that accomplish the desired result in a more practical, efiicient and satisfactory manner.

The primary object of the present invention is to more prominently delineate the elevated rim points on the drinking glass to insure observance of the sanitary purpose of the glass.

Another object of this invention is to strengthen the elevated rim points to lessen the possibility of breaking or chipping the same.

A further object of this invention is to utilize the strengthened rim points to check the roll of the glass should it be overturned.

These and other objects of the present inven tion will appear as the following description thereof proceeds, and in order to more clearly understand the invention, reference may be had to the accompanying drawing in which an embodiment of the invention is shown.

In the drawing:

Figure 1 is a perspective view of a drinking glass embodying my improved invention;

Figure 2 is a vertical section on the line 2-2 of Figure 1; and

Figure 3 is a front view of the glass overturned on a base.

In my prior patent referred to there is disclosed the idea of providing the rim of a drinking glass with a plurality of spaced elevations or points for the sanitary purpose described. However, these elevations were the same thickness as the wall of the glass. In actual use there was a tendency to overlook these points defining the drinking portions of the glass rim due to the fact they were of the same thickness as the rim and also the fragile nature of the elevations made them susceptible to breakage or chipping in normal use.

In my present invention, the drinking glass I has its rim 2 provided with a plurality, usually three, of elevations or points 3 that define the drinking portions of the rim as shown in my prior patent. However, each elevation or point 3 is thickened outwardly as shown at 4 with the thickest portion at the top center point 5 which tapers downwardly to a point 6 on the exterior of glass below the rim. The general form of the elevations or points 3 viewed exteriorly may be described as an inverted tear-drop.

The result of the thickened elevations or points 3 just described is that the drinking portions of the rim 2 are more clearly delineated or defined both visually and physically and there is no possibility of a user overlooking the same. To drink from the glass at other than the defined or guided portions of the rim would be uncomfortable and warn the user the glass was not being used as intended if the guide points were overlooked. Another practical advantage is that the thickened elevations or points 3 reinforce and strengthen the same to lessen the possibility of breakage or chipping.

As shown in Figure 3, the outwardly thickened portions 4 of the points 3 check or stop the rolling of the glass should the same be overturned. This prevents breakage of the glass in many instances.

While I have illustrated my improvements as applied to a rather thick-walled drinkin glass of the tumbler type, it may be applied to any of the various and usual types of drinking receptacles of this character.

While the device herein disclosed has been described with more or less particularity, it is to be expressly understood that the invention is not limited to said device or otherwise than by the terms of the appended claim.

I claim:

A drinking glass having a plurality of spaced elevations or points on its rim spaced apart a sufficient distance to leave room for the mouth of the drinker to engage the rim of the glass between adjacent elevations without coming in contact therewith, and said elevations being thickened exteriorly of the wall of the glass and extending below the plane of the rim in the form of an inverted tear-drop.
